MARTIN B. GROUT, OF CHICAGO, ILLINOIS, ASSIGNOR {DO KELLOGG SWITCI-IBORD AND SUPPLY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS WINDING MACHINE Application led May 23, 1924, SerialNo. 715,358. Renewed February 15, .1926.

My invention relates to winding machines which are used for winding a material, such as a strand of wire, into electromagnetic coiis. and has to do more particularly With a coil winding machine such as is used in the winding of a conducting wire upon a suitable spool to serve as a winding for an electromagnet, and an object of my invention is to provide a machine of the above ,i type which is simple in construction, and

by which the work ofv winding an electromagnetcoil may be done in a rapid, efficient and economical manner.

Various types of winding machines have been devised for winding electromagnet coils in which a distributing arm distributes the wire from a supplyr source from left to right, and vice versa. This travel of the distributing arm is controlled by suitable mechanism 3 to place the required number of convolutions :si convolutions of wire on the spool supported on the winding spindle.

Another feature of my invent-ion is the provision of a novel chuck which is secured to the spindle shaft for securing the electro- 1 magnet spool to the winding spindle during the winding operation.

Still another feature of my invention is the provision of a novel reciprocating rod or shaft Twhich carries the distributing arm and its association with a cam forbringing about this to and fro movement of the reciprocating shaft and distributing arm, as a whole. The above features of my invention, as Well as others, will be more fully described in the 45 ensuing specification.

For a more complete understanding of my invention reference may be had to the accompanying drawings inwhich like reference characters in the severalviews denote' like parts, and in which: y

Referring now more in detail to my invention as illustrated in the accompanying drawings, the winding machine comprises a suitable enclosing casing or housing 2 which enc-loses the mechanism of the winding ma# chine of my invention.

A spindle shaft 3 has secured thereto a; pulley Wheel 4 which is connected to a power shaft by means of a suitable belt, the saidA power shaft being in turn connected to a suitable starting and stopping means, and as theY power transmission for rotating the spindle shaft 3 forms no part of my invention, it is not shown in the drawings. The sides 5 and 6 of the housing 2 are provided with counter4 bores 7 and 8 through' which the spindle shaft 3 extends, and ball bearings@ and 10 are provided which rest in counter bores 7 and 8 in the sides 5 and 6 ofthe housing V2, and

The. chuck Cl which is secured to the threaded end 21 of thespindle shaft 3 comprises a body member 22 which is providedivith a` tapped orilicef23 inwhich the end 21 of the shaft 3 is threaded. The body 22 of the chuck C is provdedivith,anannular shoulder 24 which engages the ballbearing 9 and retains the same in the counter bore 7. The pulley Wheel 4 which is secured to the spindle shaft 3 is provided With anintegrally formed flange25 which has securedthereto a knob 26 by means of screws 27, andpermits the manual rotation of the Winding spindle 3When the operator prepares anew spool Which is held by theY chuck C. Y

A cam memberr 28 is provided which is tubular in form and is provided with a pair of receding helical faces 29 and 3Q, and a collar 31 ofa size to, receive the tubular cam member 28 supports the cam member 28 and secured theretobymeans. of screws 32 which passthrough suitableori'ces in the periplr eral face offthebody ofthe cam memb-er 28 and have screw-threaded engagement with suitable tappedorifices in the collar 31. The collar 31 is provided With a central orifice for receiving a shaft 33 to which the collar 31 and its supported cam member 28 are secured, asa Whole, in any suitable manner, as by means of a key or set screw. The shaft 33 which supports the collar 31 and cam member28, as a Whole, is rotatably supported in a pair, o-bearings 34 and 35 secured to the housing 2 by means of screws 36 and 36. The end of the shaft 33 which extends through the bearing 35 has secured to it a bevel gear 37 whichA meshes with a bevel pinion 381secured to atransversevshaft 39, which shaft- 39 isjrotatably supported in suitable bearings .iny the front Wall 40 of the housing2andl the rear movable cover 41. A gearwheel 42 isialso secured to the transverseshaftl39gupon which thebevel pinion 38 is secured for purposes as will presently be described. Another transverse shaft 43 rotatably supported in suitable bearings in the front Wall 40 of the housing 2 and the removable rear cover 41 has secured to it a pinion 44 and a Worm gear 45 also for purposes as Will presently be described.

A gear Wheel 46 which meshes with the gear Wheel 42 on the transverse shaft 39 and the pinion 44 on the transverse shaft 43 is adjustably and rotatably supported on an arm 47 Which arm 47 is also adjustably secured to a stud 48 which stud 48 is suitably secured. to the housing 2 in any suitable manner.

To adjustably support the gear Wheel 46 on the arm 47, the gear 46 is provided With a central orifice 49 and a counter bore 50 and a lool; nut 51 having a circular head 52 and a body portion 53 rest respectively in the counter bore and the central orifice 49 in the gear Wheel 46. The arm 47 is provided With a longitudinal slot 54 and a channel 55 and a bolt 56- provided vvith a rectangular shaped head 57 rests in this channel 55', the body of the bolt 56 extending through the longitudinal slot 54 in the arm 47. The lock nut 51 is provided with a central orifice 58 which is partially'threaded to permit screw threaded engagement with the threaded end of the bolt. Vhen the lock nut 51 andI bolt 56 arein position as just describe-d, the gear Wheel 46 is thus supported on the arm 47 and the said arm 47 and supported gear wheel 46 may now beadj usted in mesh with the gear Wheel 42 on the transverse shaft 39, and the pinion 44 on the transverse shaft 43. the bolt 56 permitting the gear Wheel 46 and its supporting parts to be moved up ordoyvn in the longitudinal slot 54 ofthe arm 47, as the case may be. When in this position, the lock nut 51 may be turned dovvn on the bolt 56 by means of asuitable Spanner Wrench for which I'lprovide apair of orifices 60 in the head 52 of the lock nut 51 to secure the gear Wheel 46 in its adjusted position in mesh With the gear wheel 42 and pinion 44. The arm 47 is provided with an integrally formed lug 61 which is split, and a bolt 62 passing through a suitable orifice in the upper split portion of the lug 61 has screw-threaded engagement with a suitable tapped oriiice in the lower splitportion of the lug 61 to clamp the arm 47 on its supporting stud 48. The gear Wheel 46 `is thus rotatably'supported on the arm 47 with the body portion 53 of the lock nut 51 forming a bearing (upon Which the gear Wheel 46 rotatesfA rlhespindle v'shaft 3 has a Worm portion 65 cutthereon and meshes with the Worm gear 45 securedto the transverse shaft 43 to which the pinion 44 is. secured. Now as the spindley shaft 3Ais rotated, the Worm 65 Which meshes with Lthe Worm gear45, causes rotation .of the said Worm gear 45, and throughthe agency4 f= right, and Vvice versa.

of the pinion 44 on the transverse shaft 43 and the gear wheel 46 rotatably supported on the arm 47 and the gear wheel 42 and bevel pinion 38 on the transverse shaft 39, and the bevel gear 37 on the shaft 33, rotary motion is transmitted to the shaft which carries the cam member 28 to cause rotation ofthe cam member 28. l

Having described the apparatus through the agency of which the cam member 28 is rotated, l will now describe the mechanism associated with the cam member 28 and reciprocating shaft 70 for causing the movement of the reciprocating shaft 70 from left to The distributing or reciprocating shaft 70 is slidably supported in bearings 71 and 72 in the sioes 5 andG of th-e housing 2, and has secured to it a cam follower member 73 suitably securedto the reciprocating shaft 70 by means .of a clamping screw 74. The cam follower member 73 is p-rovided with a knife edge nose 75 which is held in engagement with either of the' faces 29 or 30 of the cam member 28, de-

" pending upon the position of the cam member 28, by means of a helical spring '76 around the shaft 70, and which spring 76 has one end secured to a. suitable hook vmember 77 secured to the side of the housing 2, the other end of the spring 76 being secured to the cam follower member 73 in any suitable manner.

Referring now to Fig. 1 l show a .distributor 80 secured to the distributing or reciproeating shaft 70 by means of a suitable clamping member 81. The goose neck arm 82 which supports the ball bearing guide wheel 83 is provided with a threaded end which extends through suitable orifices in the clamping member 81 and nut 84 having screw-threaded engagement with the threaded end of the goose neck arm 82 secures the said arm 82 and its supported guide wheel 83, as a whole, to the member 81, and also clamps the member 81 to the distributing or reciprocating shaft 70. The distributing arm 80 is shown in its extreme left position and ready to start on its travel to the right. At that instant, the nose 75 of the cam follower member 73 has just passed theapex 85` of the cam member 28, causing the distributing or reciprocating shaft 70 to start its travel to the right, and the continued rotation of the cam member 28 permits the cam follower member 73to follow the receding pitch or contour of the cam face 29 and, as

the follower member 73 is secured to the reciprocating shaft 7 0, the tension of the spring 76 is such as to draw the distributing or reciprocating shaft 70 to the left with refer ence to the rear view of Fig. 4, and to the right with reference to Fig. 1.

Now, when the nose 75 of the cam follower 73 rea-ches the base 90 of the receding pitch face 29 of the cam member 28, the nose 75 again engages the face and rides upon the pitch face 30 of the cam member 28, and the continued rotation of the cam member 28 causes the nose 75 to follow the contour of the pitch face 30 and forces the cam follower 73 to the right with reference to Fig. 4, and as the vfollower is secured to the reciprocating shaft the shaft 70 is also moved to the right again placing the spring 76 under tension."

j From the above description it may be seen that the rotation of the cam member 28 through the agency of the cam follower 73 brings about the movement of the distributing or reciprocating shaft 70 from left to right, and vice versa, and that for one complete revolution of the cam member 28, the distributing or reciprocating shaft 70 will have traveled from left to right and from right to left, and as the distributing arm 82 is secured to the shaft 70, two layers of convolutions of wire have been placed on the spool 95 gripped by chuck C secured to the spindle shaft 3. l provide a guide arm 96 secured to the reciprocating shaft 70, which is provided with a bifurcated end 97 which straddles a rod 98 secured tothe side 5 of Y vide a plate member 99 suitably secured Yto .a

bracket 100 which bracket 100 is in turn secured to a rod 101 secured to the side 5 of the housing2.. vThis plate member 99 is for the purpose of placing strips of paper thereon, and which may be interposed between the layers at intervals, sothat the winding will buildup evenly so as to furnish a foundation for the next few layers and so on throughout the coil at the will `of the operator.

The chuck for gripping` the electromagnet spools is provided with a body portion 22 which, as already described, is secured to the spindle shaft 3. The body 22 is provided with slots 102 in which the jaws v103 are pinned b v the pivot pins 104. An internally threadedring member 105 has screw-threaded engagement with the threaded porti on 106 of the body 22 of the chuck. and is provided with an annular internal lip 107. The jaws 103 are provided with tapered faces 108 and through the agency of a helical spring 109 which rests between the jaws 103 and the bottom of the slots 102, the free ends of the jaws 103 are forced outward. The vbody portion 22 is also provided with a threaded stud 110 integrally formed therewith, and

the core of the spool 95 in its one end is provided with a suitable tapped orifice .which is adapted to be threaded on the tapped stud 110 to rotatably secure it to the spindle shaft Y housing 2 by suitable screws 112 which have screw-threaded engagement With nitable tapped orifices in the housing 2. This cover may be removed to permit access to the mechanism of the machine. rEhe housing 2 is also provided with va suitable base 113 and the machine may be secured to a suitable bench and a Wire strand 114- from a suitable source led over the guide Wheel 83' of the distributing arm to the spool 95 to be Wound.
